Additionally, he said the category was improving; he credited the tops sector's positive sales in part to to the success of the new, looser silhouette, saying that consumers could layer it.

(Another perk that Potdevin didn't mention of the looser silhouette? It can conceal bloat; something, that, all body positivity aside, can make even the most confident women self-conscious from time to time.)

Wells Fargo points out that the tops business takes up more floor space than bottoms do.

In 2015, the company reinvented its pants business with a new "Pant Wall," through which it organized pants by "sensation," thereby making it easier to people to shop for pants. For fiscal 2015, total comparable sales skyrocketed 10%.

Further, this "bodes well for the tops opportunity later this year," Wells Fargo writes, as the company has plans to launch a similar type of setup for tops.
